IMPROVEMENT IN PITMEN.

Specicationforming part of Letters Pafw/eltpq; 1412,611, dated September9,1873; application filed Amira-1873.

To all whom it may concern:

Be it known that I, JACOB H. CAROTHERs, residing in Lewisburg,in thecounty of Union and State of Pennsylvania, have invented a new anduseful Improvement in Pitmen, of which the following is a full, clear,and exact description, reference being had to the anneXed drawing, inwhich the ligure illustrates a perspective View of my improved pitman.

This invention relates to pitmen composed of two parts united by meansof springs, by Which they are rendered susceptible of clon gation andcontraction. My improvement consists in the combination, with such apitman, of a spring and cushion interposed between the parts thereof7 aslotted sleeve, and a pin or projection, secured, respectively, to thelatter, substantially as hereinafter mere fully set forth. f

To enable others to make and use my invention, I will proceed todescribe it.

The pitman A A is composed of two parts united `by the coiled spring Bor other suitable means by Which the pitman may be made susceptible ofcontraction and elongation or yielding, so as not to check the speed ofthe m achine When in motion-an objection to Which the ordinary pitman isopen, in consequence of its stiffness or inelasticity. The speed of themachine is thus prevented from being checked by the pitman yielding tothe inequalities of the motion thereof. To form a cushion for andinterposed between the opposite ends of the parts of the pitman is ablock or cylinder of rubber, C, encircled by the coiled spring B. Thisblock of rubber or cushion C also prevents the contact of the ends oftheparts of the pitman, by which all concussion is overcome. A sleeve, D,is fitted to one of the parts of the pitman, and having an elongatedslot, d, which receives a lug or projection, f, fastened to a ring orcylinder, F, confining the Opposite end of the coiled spring B to theother part of the pitman. The ring or band F acts to relieve the sleeveD of friction as it slides back and forth over the band F.

It is obvious that when a metallic pitman is employed the friction-bandF can be dispensed with.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

The combination of the pitman A AWith the spring B, cushion C, sleeve Dd, and pin or projectionf, substantially as and for the purposespecified.

In testimony whereof I havehereunto signed my name this 25th day. 0fMarch, 1873, in presence of two subscribing Witnesses.
